| 摘要 |
A thermoelectric element has a first substrate at a high temperature side, a second substrate at a low temperature side facing the first substrate, a thermoelectric material placed on the second substrate via a silicon layer, a first electrode formed on the first substrate, and a second electrode formed on the silicon layer. The thermoelectric element has a stress releasing section which is formed between the first electrode and the thermoelectric material, and which includes a plurality of columnar portions. The stress releasing section suppresses defects such as cracks that might be produced in the thermoelectric element due to a stress generated in the thermoelectric element. |
